Evaluation and clinical application of 3D-CTA imaging techniques in the diagnosis of intracranial aneurysm

Objective: To investigate the value of clinical application and diagnostic accuracy of 3D-CTA imaging techniques in the diagnosis and treatment of intracranial aneurysm.Methods:Final diagnosis were made in 42 cases of intracranial aneurysm through 3D-CTA,comparative study of 3D-CTA images and operation results were performed.Results:The procedure of exposure aneurysm was identical with the 3D-CTA image.In 40 cases,the operation results were identical to the result of 3D-CTA.Misdiagnosis were found in two cases.Conclusion:3D-CTA should be used as the first choice for clinical diagnosis of intracranial aneurysm,and is an important reference for the surgical planning before operation.For the anterior communicating artery aneurysm or post communicating artery aneurysm,MIP and SSD techniques should be used for further diagnosis.
